Any casual reading of the gospels shows that Jesus message and life was centered on the Kingdom of God (The Rule and Reign of God on earth). Since ‘the reason the Son of God appeared was to destroy the devil’s work’ (1 John 3:8), he inevitably came into collision with the prince of darkness. The signs of the Kingdom were evidences that the devil was retreating before the advance of the King. This was manifest in many different ways ‘signs.’. Jesus called us to preach the Kingdom of God and expected his disciples to do likewise; Luke 9:1-2.
Jesus not only proclaimed the Kingdom of God, he also demonstrated its reality with ‘signs of the Kingdom’, public evidence that the Kingdom he was talking about had come‘… if I cast out devils by the Spirit of God, surely the Kingdom of God has come upon you (Matt 12:28)’ When Peter wanted to explain who Jesus was and what He was about, he said in Acts 10:38 , ‘He went around doing good and healing all who were under the power of the devil because God was with Him.’ As ‘Christians’ (meaning little Christ) we should live up to the name and live likewise.
Luke starts his account in Acts 1:1 by saying that we was , going to make an account of all Jesus ‘did’ and ‘taught’.
Jesus told His disciples that they would communicate to the people in the villages that the Kingdom had come by the demonstrations of the kingdom that they showed (Luke 10:9, Matt 12:28 and Luke 11:20)
‘As you go, preach the message … heal the sick’ Matthew 10:7-8
John 14:12 I tell you the truth, ANYONE who has faith in me WILL do what I have been doing. He WILL do even greater (Greek root ‘mega’) things than these.’
When John the Baptist wanted to know if Jesus was really who he said He was, He did not say look at might titles… He said look at what I am doing. He showed authorised himself by what He did. (We try to explain it by apologetics, theology), Jesus did not do that. Also when other people asked Him who He was and where His authority came from, He just did miracles to answer. How do we answer?
John 2:23 ,’many believed in His name when they saw the signs which he did.’
‘And they went out and preached everywhere, while the Lord worked with them , and confirmed the word by the signs that followed.’ (Mark 16:20, emphasis added). God confirms His word through miracles, signs and wonders. As 1 Corinthians 4:20 says, ‘The Kingdom of God is not a matter of talk and power.’ . The bold declaration of the Gospel of the Kingdom brings the God of miracles to the forefront: ‘Now, Lord, look on their threats, and grant to Your servants that with all boldness they may speak Your word, by stretching out Your hand to heal, and that signs and wonders may be done through the name of your holy Servant Jesus Acts 4:29-30
‘My speech and my preaching were not with persuasive words of human wisdom, but in demonstration of the Spirit and of power, that your faith should not be in the wisdom of men but in the power of God.’ 1 Cor 2:4-5 (also 1 Cor 4:20)
Therefore ‘Integrity in the Kingdom of God is to witness and testify of a powerful God and then move in the power we proclaim- witnessing, preaching, and testifying without the power of God is duplicitous. ‘ That way like Paul we can say we ‘fully proclaimed the gospel of Christ’ (Romans 15:17-19)
